From what I can see, the metallic square that look like a potentiometer just beside is probably the "Ceramic discriminator" mention in the datasheet. Some sort of reference for the sonar signal I guess?My problem is I have no clue of where I can take the data out of the HT chip and if I will need to condition the signal for the arduino? device for GPS, Fishfinder, Echosounder, Compass and battery indication and all displayed in a color screen!

Tags two fish sizes under and over 38 cm. ibobber syncs with ios 6.0, 7.0 and 8.1 operating systems (apple). phone and tablets for android (v4.3), using bluetooth smart v4.0.Do you think that the data are produce in the HT or maybe the HT only receive the numbers from another chip and just drive the LCD? In such case, my point would be to connect on the data in pin of the HT not on the data out to lcd pinssssss. Finally, can someone explain my the basic of coil inductor (the 2 metallic square coil on the board). I google about this. They have 5 pin. 3 on one side and 2 on the other. I think the 3 pins are like potentiometer that allow to adjust the coil inductance value. The other end is fix and will act like a transformer? In any case, both coil inductor are not clearly connected to an IC. There is some transistors in between. I try to follow the signal path but my misunderstanding of the 5 pin vs the transducer input make this job much harder. I also think that the inductor on the rigth is only for reference signal since I don't see any connection with the transducer while the other one is connected to the transducer. Wave rider motion responsive design: one of the most essential deeper accessories. adjusts by up to 20cm while mounted, allowing deeper sonar to remain on the surface to ensure constant connectivity with your smartphone. I took a different example of the same "brand" of fishfinder apart, and was daunted by a separate small circuit board that has at least 3 tuned circuits, and several different connections to the micro. That was too much of a challenge for me, but yours looks a lot simpler. You will almost certainly need an oscilloscope to trace the signal paths.
